Hello group,
I still have problems creating snapshots on my Ubuntu Linux box. Most of
the time, snapshots can't be created with an strange error message. I
startet the lvcreate with very verbose output, so you can see all the
gory details.

I don't have an idea why "deactivating" of the snapshot wont work and
what this for.
I'm using Kernel 2.6.20-16-server
dmsetup -v version
Library version: 1.02.08 (2006-07-17)
Driver version: 4.11.0
Any hints?
thanks in advance
